For people with visual disabilities like Glaucoma or Diabetic Retinopathy,
vision loss is a fact of life that they have to live with. Eyetonomy thinks it
has the answer to helping people with visual impairments see better and it’s
called the SightMate.

This camera has a 2 megapixel sensor coupled with a 3x optical zoom. Inside
the glasses the wearer looks at twin high-resolution 640 x 480 pixel displays
that can tilt up to 15 degrees for comfort. The device can also compensate for
colorblindness.

The entire system weighs eight ounces and has a controller that weighs less
than one pound with the batteries installed. The controller allows the
wearer to zoom in and out on objects and control other functions of the system.
According to SightMate clinical trials have shown that people with between
20/70 and 20/200 acuity in their best eye have been able to increase their
reading and distance acuity to a range of 20/20 to 20/40.

The device also uses edge detection and color correction in concert with the
optical zoom to assist users who suffer from gradual visual loss over the
entire field of view. SightMate warns that the device is designed to be used
while sitting and not designed for use with anything requiring motion like
walking or driving.

Eyetonomy sells the SightMate LV920 for $3,499, which seems expensive considering
that similar video glasses go for well under $1,000. The other problem with
SightMate is that the device looks quite odd.

It will be hard to get those conscientious about their appearance to use
this device. However, for use in the home this may be a good stop gap for
people with failing vision until something else, like contact
lenses with embedded electronics are available.
